Answer 2

Answer:

2 hours 15 minutes

Step-by-step explanation:

Time = 2 hours 30 minutes

       = 2 * 60 + 30

      = 150 minutes.

Thus, pipe take 150 minutes to fill 250 liters tank.

=> (9/10) * 250

=> 2250/10

=> 225.

So, to fill 1 liter tank it will take 150/250 minutes.

=> (150/250) * 225

=> 135 minutes

=> 2 hours 15 minutes
